Abstract

Frequency and voltage scaling are performed for each virtual processor in a virtual environment. The characteristics of the workload performed by each virtual processor are dynamically profiled and a scaling algorithm determines a scale factor for that virtual processor as a function of the profiled characteristics. The profiled characteristics may include virtualization events associated with the workload being performed. In addition, a particular scaling algorithm and profiling technique may be selected based on which virtual processor is currently running.
